Hello,
I am seeing a kernel oops when booting 2.6.0-test5-mm4. Below is the oops.
Looks like it is from the ACARD driver, since when I disable it in the
kernel, the oops no longer happens. This is a dual Xeon 866 (Dell Poweredge
4400) with an SMP kernel. I hope the ksymoops is useful.
Regards,
--Eric

<0> Kernel Panic: Attempted to kill init!
1 warning and 2 errors issued. Results may not be reliable.
The driver's probe function accesses uninitialised data. I also made it
use pci_get_device instead of pci_find_device to bump the refcount on the
pci devices it finds.

I don't suppose you'd like to fix this properly? i.e. convert the
driver to the sysfs based pci probing infrastructure and remove its
dependence on MAX_ATP arrays?

Sure, i can do that.
